Abstract: The system and method for social distancing compliance generates an alarm when at least two people are separated by a distance that is less than a predetermined threshold value. Thermal imaging is used to detect at least two people using at least one thermal image sensor. At least one distance is calculated between the at least two people, and it is determined if the at least one distance is less than a predetermined threshold value. If the calculated at least one distance is less than the predetermined threshold value, at least one of the at least two people is alerted that a minimum safe distance is not being met.
